Key Takeaways:
- 1. A $252 billion option for missile defense includes additional Patriot missile batteries, aircraft, and next-generation defense systems.
- 2. A more comprehensive $3.6 trillion plan aims to provide the most robust air and missile defense shield by 2045.
- 3. Deploying up to 2,000 space-based interceptors could cost between $161 billion and $542 billion over 20 years.
Different missile defense options range from a $252 billion plan focusing on existing technologies to a $3.6 trillion proposal for a comprehensive air and missile defense shield. Deploying space-based interceptors, though costly, is seen as more feasible now due to lower launch prices and increased satellite production capabilities.
Insight: SpaceX's Starship rocket could potentially lower the costs of deploying space-based interceptors, making the concept more viable than in the past.
